AUTQMATIC ADJUSTING MEANS HEADLIGH TS.

Specification of Lcttefs Patent.

Patented Mar. 28,

Application. filed March 81, 191.6. Serial No. 552,688.

To all whom it may concern:

Be it known that I, Josnrn P. MoELLIo'rr, a citizen of the UnitedStates, and a res1 dent of Toledo, in the county of Lucas and State ofOhio, have invented a certain new and useful Automatic Adjusting Meansfor Headlights; and I do herebydeclare the following to be a full,clear, and exact descripportion of my .re central sectional and ,planviews of on, which form a which is automatically actuated to tion of theinvention, such as will enable' others skilled in the art to which itappertains to make and use the same, reference being. had to theaccompanying drawings, and to the figures of reference marked therepartof this specification.

My invention relates to railway appliances, and has particular referenceto means move the headlight of alocomotive, electric car, or othervehicle of a self-propelled nature to cause the reflected light tofollow the curves of a track over which the locomotive orthe like isoperating.

The object of my invention is the provision o a simple and efi'icientapparatus of the class described, which is an improvement upon theapparatus described and claimedin the application for United StatesLetters Patent filed by me on June 10th, 1909, being Serial No. 501,444,and which is economical in its construction, positive in its action andadapted to adjust the headlight vertically as well as horizontally tocause the light rays to be directed on the track as far in advance ofthe locomotive as the nature of a curve which the track is followingwill permit.

The invention is fully described in the following specification, and apreferred embodiment of the same illustrated in the accompanyingdrawings, in which,

Figure l is a side elevation of the front portion of a locomotive,partly in section,

with my invention in operative association therewith. Fig, 2 is a frontelevation of the same with a portion of the locomotive broken away. Fig.3' is a plan of the lower inventidn, and Figs. i and 5 v the -:adlightsupporting'hrocket.

Referring to the drawings, 1 designates any suitable form of locomotive,the front truck -2 of which is provided with a verlight for verticalportion or ledge of the bracket 10 1S down one of planes of the cam 153and tically disposed axial trunnion or turning bolster 3, which iscommon in one form or another in most locomotives.

4 designates the locomotive headlight, which. is shown as having itsdrum or casing circuinferentially encircled by a hand 5, the ends ofwhich are detachably secured t0- gether by a bolt or screw 6., This handhas trunnions 7 projecting therefrom at the sides of the headlight,which trunnions journal in the'ends of a semi-circular supporting cradle8, carried at the upperend of a vertical shaft 9, thus adapting theheadoscillatory movements with the trunnions 7 as its axis, or forhorizontal oscillatory movements with the shaft '9 the axis.

The shaftt has its upper end journaled in a bracket 10 projectinghorizontally'from the front end of the locomotive boiler, and has itslower end journaled in a bracket 11. carried by the usual frontcross-beam 12 of the locomotive. The horizontally proj ecting rovided onits upper sarface beneath the orward portion of the headlight with asegmental inverted l-shaped cam 13 the point or apex of which isdisposed hcneath'the central portion of the headlight when di rectedstraight ahead. Beneath the rear edge of the headlight the bracket 10 isprovided with a'seginental ll-shaped cam 14 the top or cam surface ofwhich is exactly the reverse of the top or cani surface of the front cam13. The headlight is provided on its under side adjacent its front andrear edges with substantially V-shaped lugs 15 and 16, respectively,which rest upon the respective cams l3 and is as indicated. The cams 13and 14 and the lugs 15 and 16 are so relatively arranged that when thehead light is ie'straight-ahead position it is at a neutral point of itsvertical oscillatory adjustinent with the front lug coacting with thecentral or highest point of the cam 13 and, rear lug coacting with thecentral or lowest point of the cam l l. A. turning of the headlight ineither wa upon its vertical axis will cause the front lug to ride thedownwardly declining the rear lug to ride up the reverse upwardlyinclined plane of lit) wail

light on its horizontal axis for termined degree of horizontal turningeither direction.

The lower end of the shaft 9 has arms 17 projecting horizontally 'lron'itnn'iosite sides thereof laterally of the loromotive such arms being"preferably angled rearwardly from the shaft. to provide a space, betweenthem and the cross-bean! 12 in which the arms may rock. A couplingmember 18 is an- I'iBtl by eaeh arm 17 for longitudinal adjust mentthereon, it being secured in adjusted position by a set-screw 19.

Links or rods 20, 20 extend rearwartily from the 111?]1'15 1.7. 17 beingpivotally attached thereto through the ineditnn ot the eonplinr a l8.18, or in any other snitahle manner, and have their rear ends extenrlin;on opposite aides of the trurk trunnion or J, and pirot'aliy attached toears 2t holster projecting from opposite sides of a hand or ring 22,wlneh encircles and 1S firmly clamped to auoh trunnion to turntherewith. For this purpose the hand is Fllt flll as being inatle in twoparts clamped together by holts Q3. The degree of turning oi the shalt 9tor a. predetermined turning of the trunnion $5 is regulated by anadjustment of the couplings 1.8 on the arms l7.
